"We are talking about several hundreds, possibly thousands of sets of remains," Crossrail archaeologist Jake Carver told the newspaper at the time. "We have made a larger hole at the site than anything previously created here."

The cemetery was officially known as the "Bethlehem Churchyard," which was part of Bethlehem Hospital's land holdings. "Bedlam" was an old abbreviation of Bethlehem and eventually became connected with the hospital, which was known for its inhuman treatment of patients, The Independent noted.

"There are up to six meters of archaeology on site, in what is one of the oldest areas of the city, so we stand to learn a great deal," he continued. "The research also aims to shed light on migration patterns, diet, lifestyle, and demography of those living in London at the time. Excavated skeletons will be taken to MOLA for testing by osteologists (bone specialists) before being reburied in a consecrated burial ground."

Crossrail was established in 2001 as a joint venture company between Transport for London and the Department for Transport, before becoming a fully owned subsidiary of Transport for London in 2008.

Crossrail wrote that the Bedlam cemetery was in use from 1569 to at least 1738, through the British Empire and various plague outbreaks. Archaeologists hope that testing plague victims from the burial grounds will help to understand how the bacteria strain evolved.
